This invention relates to winding machines for winding thread, yarn, wire or other strand material into cops, cones, coils or other types of packages and more particularly to a self-contained, angularly-adjustable spindle and driving unit for such machines.

For convenience of description the material to be wound will hereinafter be referred to as yarn and the wound mass or body produced on the machine as a "package; it being understood that these terms are to be construed broadly as designating any kind of strand material, whether textile or otherwise, and any form of cop, cone, coil or package wound therefrom.

One object of the present invention is to provide a winding machine of the type indicated having a positively driven winding-spindle which is angularly adjustable with respect to the traversing mechanism to wind either cylindrical or conical packages of any angular taper.

Another object of the present invention is to provide a machine of the type indicated having a self-contained unit, including a. spindle and its driving mechanism, which is adjustably mounted on the machine frame to provide for altering the 26 angular relationship of the spindle with respect to a relatively-fixed traversing mechanism.

Another object of the present invention is to provide an angularly adjustable spindle and driving unit of the type indicated comprising an electric motor having the opposite ends of its annature-shaft extended to form the winding-spindle and a drive-shaft for the traversing mechanism.

Still another object of the invention is to provide a winding machine of the type indicated which is of simple construction, eiilcient and economical in its operation and adapted for use over long periods of time without repair or replacement of its parts.

Further objects of the improvement are set forth in the following specification which describes a preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings.

In the drawings:

In winding machines of conventional type as 15 heretofore used the winding-spindle is journaled in the machine frame in fixed bearings. To adapt such machines to wind conical packages it has heretofore been necessary to alter the form of the traverse-frame carrying the thread-guide to cause the latter to oscillate toward and away from the axis of the package to a greater or lesser degree as it is reclprocated along its periphery. Usually the winding-spindles of such machines are driven by belts connected to a continuously 25 driven countershaft or in other cases to a continuously operated motor.

The present invention provides for quickly and easily adjusting the angular relation of the winding-spindle with respect to a traversing mecha- 3 nism so that either a cylindrical or conical package may be wound on the machine without changing the traverse-frame back or the direction of motion of the thread-guide. Further, the present invention provides an individual motor drive 35 for each spindle so that only those spindles need be driven which are performing a winding operation while also eliminating the use of belts, pulleys, countershafts and belt-shifters or clutches for connecting the drive. 40

The present machine comprises in general a main frame or casing having a traverse-frame pivotally mounted thereon for swinging movement about a fixed axis and a cooperating winding-spindle formed as an extension of the arma- 45 ture-shaft of an electric motor. The motor is mounted on the main frame for adjustment about a vertical axis to alter the angular relation of the spindle with respect to the traverse-frame on which the thread-guide reciprocates to wind 50 a package; and means are provided for clamping the motor in any adjusted position. The motor is controlled by a circuit-breaker which is arranged to be manually operated to close the circuit and automatically operated to open the cir- 5s cuit when the yarn breaks or the package attains a predetermined size. The present invention also provides an actuating mechanism for the circuitbreaker comprising separate elements on the main frame and motor, respectively, and selfadjusting means for connecting these elements to permit angular adjustment of the motor with respect to the main frame.

Referring to Figs. 1 and 2 of the drawings, one

winding head of a series is herein shown as mounted on a suitable bed which may be extended to support any desired number of winding units. The operating parts of each winding head are mounted on a box-like frame 2 having an upper horizontal platform 3 for supporting the self-contained and angularly-adjustable spindle and driving unit 4, to be later described in detail. Suflice it to state here that the unit 4 includes an electric motor having its armature extended to form a winding-spindle 5 overhanging one side of the frame and a drive-shaft 5 overhanging the opposite side of the frame. The winding-spindle 5 may be so constructed as to support either a cylindrical or conical package and in the latter case it carries a suitable form of cop-holder 1 to receive a tapered cop-tube C on which the package is wound.

Below the winding unit 4 the frame 2 carries bearings 8 in which a cam-shaft 9 is journaled. Fast on the cam-shaft 9 is a cam l5 having a cylindrical rim IS in which a helical groove I1 is formed. The cam I5 is connected to reciprocate the thread-guide l8 which is of usual construction having a head l9 formed with a groove or slot 20 through which the yarn y feeds to direct it onto the package being wound. The thread-guide I8 is carried at the end of a horizontal rod or traverse-bar 2| which is connected to a slide or crosshead 22 having a bowl or roller 23 engaging the helical groove ll of the cam l5.

The thread-guide l8 and its reciprocable traverse-bar 2|, together with the connected crosshead 22, are arranged to slide in a traverse-frame 2'1 rockably supported by the cam-shaft 9. As shown in Figs. 1 and 2 of the drawings the traverse-frame 21 comprises a horizontally-extending member 28 formed with suitable grooves or guideways for the crosshead 22 and traverse-bar 2i and provided with opposite legs 29 and 30 straddling the cam l5 and pivotally mounted on the cam-shaft 9. The legs 29 and 30 of the traverseframe 21 have hubs at their ends surrounding bushings 3i and 32 in the bearings 8 on the frame 2 of the machine which serve as the journals for the cam-shaft 9. The outer leg 29 of the traverse-frame 21 is extended below its bearing hub, preferably in a separate arm 33 attached thereto and terminating in a counterweight 34 which tends to maintain the frame in substantially erect position. Attached to the overhanging part of the traverse-frame 21 is a plate or back 35 against which the thread-guide l8 bears to direct it in a course parallel to the surface on which the winding is performed. In the present illustration of the machine the traverse-frame back 35 has its bearing face 36 extending parallel to the fixed axis of the camshaft 9 on which the traverse-frame is pivotally mounted.

The cam-shaft 9 may be driven from the driveshaft 6 in a manner common to machines of the present type to give the thread-guide l8 a continuous lead or gain. As herein shown the drive comprises reduction gearing enclosed in a housing 40 formed. as a part of the bushing 32 and rotatable on the cam-shaft 9. The housing 40 has a bearing for a stud-shaft 4! for driving the reduction gearing and on which a driven pulley 42 is rigidly fixed exteriorly of the housing. The pulley 42 is driven by a belt 44 passing over a pulley 43 fast on the drive-shaft 6. The pulley 43 is of the usual expansible type having a tapered thimble 45 longitudinally adjustable on its hub 46 to force the spokes 41 radially outward to expand the split. rim of the pulley. In this manner the diameter of the pulley 43 may be altered to adjust the speed ratio between the spindle 5 and cam-shaft 9 to give the desired gain to the thread-guide 18 in accordance with the size or count of the yarn being wound. The housing 40 and pulley 42 are rocked about the cam-shaft 9 to tension the belt 44 by means of a weight 48 at the end of a cord 49 which is looped through an eye 50 on the housing and attached at its opposite end to a fixed pin 5|. The peripheries of the pulleys 42 and 43 are crowned to hold the belt 44 in driving engagement therewith when the driving pulley 43 is angularly positioned with respect to the driven pulley 42. The forward end of the cam-shaft 3 projects beyond the hub of the traverse-frame 21 and carries a toothed wheel 52 of usual construction for actuating the stopping mechanism of the machine in a manner as later explained.

The present invention is directed particularly to the self-contained spindle and driving unit 4 for providing angular adjustment of the windingspindle 5 with respect to the traverse-frame 21 so that either cylindrical or conical packages may be wound without change or substitution of any of the parts of the machine. The spindle and driving unit 4 is comprised of a frame or mounting which may be of any suitable form for rotatably supporting the winding-spindle 5 together with its driving means, and of such construction as to provide for its angular adjustment about a vertical axis on the horizontal platform 3. In the preferred embodiment herein illustrated the unit 4 is in the form of an electric motor having the usual frame or casing 53 in which the armatureshaft 54 is journaled with its extended ends constituting the winding-spindle 5 and drive-shaft 6.

Preferably, the motor is of the three-phase induction type to eliminate fire hazard and provide for ease in starting, but it may be of any other suitable type whether induction or repulsion, direct or alternating current, single or multiple phase. As illustrated in Fig. 2 the motor includes the usual armature 55 fixed to the shaft 54 and cooperating field coils 56 carried by the casing 53 interiorly thereof. The casing 53 is provided with a flat base formed by laterally-extending feet 5'! for mounting the motor on the platform 3, the feet having narrow slots 58 open at their outer ends.

The motor is adjustably mounted on the frame 2 for movement about a vertical axis constituted by a stationary pin 59 extending upwardly from the horizontal face of the platform 3 and engaging a slot or recess 60 in the motor casing 53. The slot 60 is preferably elongated to provide for a slight adjustment of the unit longitudinally of the main frame 2. The motor casing 53 is clamped in any position of angular adjustment on the platform 3 by means of bolts 6| arranged in any suitable manner on the main frame 2 to extend through the slots 58 in the feet 57. As herein illustrated the heads of the bolts 6| are held in inverted T-shaped slots 63 formed in the platform 3 with their threaded shanks projecting upwardly through the slots 99 in the feet 51. The slots 59 in the feet 51 of the casing 59 and the slots 99 in the platform 9 permit sliding movement of the bolts 9| during angular adjustment of the unit 4 about the pivot-pin 59, after which nuts 94. are screwed down on the threaded shanks of the bolts into binding engagement with the feet of the casing. It will be understood that the unit 4 is adjusted from the position shown in Fig. 3 to that shown in Fig. 4 or into other angular relationship by loosening the nuts 94 on the bolts 9| and turning the unit 4 bodily until the windingspindle 5 is at the desired angle with respect to the traverse-frame back 95.

The armature-shaft 54 is journaled in bearings in the end bells of the motor which are preferably of the form illustrated in the drawings. As

. herein shown, one end-bell 91 is formed integrally with the motor casing 59 while the opposite end-bell 99 is detachably secured to the casing by screws 99. The end-bells 91 and 99 are provided with alining bores I9 through which the armature-shaft 54 extends and surrounding the bores 19 are hollow cylindrical housings II and 12 in which similar bearings 19 are mounted. The bearings 19 are preferably of the antifriction ball-bearing type having their outer races fixed to the interior of the housings II and 12 and the inner races held between shoulders 14 and nuts I5 screwed onto threaded portions I9 of the armature-shaft 94. The housing II is closed at its outer end by a plate 11, while the housing 12 is closed by an adjustable gland I9 having screwthreaded engagement with the interior of the housing and engaging the outer race of the bear ing I9 to prevent end thrust. The lubricant for the bearings I9 is prevented from escaping from the housings II and I2 by packing between the shaft 54 and end-bells 91 and 99 and the end plate l1 and gland 19.

The drive-shaft extension 9 is shown as integral with the armature-shaft" while the winding-spindle 9 is preferably detachable therefrom.

A form of detachable spindle 9 for winding a cylindrical package, as illustrated in Figs. 2 and 3, has a reduced threaded end-portion 99 screwed into a threaded bore 9| in the end of the armature-shaft 54. The outward end of the spindle 5 is split at 92 and adapted to receive the threaded end of a tapered expanding screw 99. As the expanding screw 99 is screwed into the spindle 5 the split end of the latter is expanded to bind it against the interior of a cylindrical cop-tube C. A sleeve 94 secured to the shaft 54 and spindle 5 by set-screws 95 carries the usual grooved brake-wheel 99. When a conical package is to be wound the spindle 5 is detached from the armature-shaft 54 and another spindle applied carrying a suitable holder I for a tapered coptube C for use in winding a:. conical form of package. The tapered cop-tube holder I, as disclosed in Fig. 4, is of well known construction comprising a plurality of segments or springfingers 91 having serrations 99 at their ends for engaging a conical cop-tube C. The segments are expanded by sliding a sleeve 99 inwardly on the spindle 5 to cause it to ride under internal cam-faces 90 on the segments, the sleeve being actuated by a control handle as later described.

The motor current is controlled by a circuitbreaker 9I mounted on an arm or bracket 92 fastened to the motor casing 59. As shown in detail in Fig. 5 the circuit-breaker is enclosed in a casing 93 and comprises pairs of oppositelydisposed contact-fingers 94 and 95, one for each phase winding of the motor, with the fingers extending inwardly from the sides of the casing. A plunger-rod 99 of suitable nonconducting material is mounted for longitudinal movement in the casing 99 and carries metallic bridging contacts 91 thereon. The rod 99 extends beyond the ends of the casing 99 and at one end has a pushbutton 99 while at its other end is a cross-pin 99 for limiting upward movement of the rod with respect to the casing. Surrounding the rod 99 between the push-button 99 and casing 99 is a spring I90 for normally holding the bridging elements 91 out of contact with the contact-fingers 94 and 95 to maintain the circuit open.

As shown most clearly in Fig. 1, the plungerrod 99 of the circuit-breaker 9| is actuated to bridge the contacts 94 and 95 to close the circuits and energize the motor by a lever IOI engaging the push-button 99. The lever MI is pivoted on a pin I02 fixed in the motor casing 59 above the bearing housing II. The lever MI is normally rocked about the pivot-pin I02 in a counterclockwise direction by a spring I09 tensioned between one arm of the lever and the motor casing 59 to hold the opposite end of the lever in inoperative position. The lever IOI is adapted to be rocked in a clockwise direction to depress the plunger 99 to circuit-closing position by means of a handle I04 rockably mounted on a hub I91 which is pivoted on the pin I92 and connected with the lever by pins I95. The assembly of lever IOI and handle I04 are held against axial movement on the pivot-pin I92 by a set-screw I99 extending through the hub I01 and into a groove in the pin, see Fig. 2. The handle I04 is pivoted on a pin I24 held in lugs I25 on the hub I91 to also adapt it for pivotal movement in a plane at right-angles to its plane of movement about the pin I02. The handle I04 is rocked manually in the latter direction to actuate the sliding sleeve 99 of the cop-tube holder I in a well-known manner.

The lever IN is held in circuit-closing position against-the actions of the springs I00 and I99 to maintain the machine operative by suitable detent mechanism as next described. The detent mechanism comprises a curved arm I26 extending from the hub I01 around the periphery of the brake-wheel 99 to a position below the armature-shaft 54. At its lower end the arm I29 is provided with a projecting detent or locking lug I99 which is adapted to be engaged by a correspondingly-shaped lug I09 carried at the end of one arm of a bell-crank lever I I9, see Fig. l. The bell-crank lever H0 is pivotally mounted on a stud III projecting from the motor casing 59 and is adapted to be rocked in a counterclockwise direction to release the detents I09 and I09. The spring I09 will then act to rock the lever IOI while the plunger-rod 99 of the circuit-breaker 9| is raised by the spring I00 to open the circuits to the motor. The curved arm I29 extends beyond the hub I01 on the opposite side of the pivotpin I02 and at its end carries a pivotally-mounted brakeshoe II3 for cooperating with the brakewheel 99 to arrest the rotation of the windingspindle when the circuit-breaker is opened.

The bell-crank lever H0 is held in looking engagement with the end of the curved arm I29 by means of a quadrant I I4 pivotally mounted on a stud II5 projecting from the side of the main frame 2. As shown in detail in Fig. 6, the longer arm II2 of the bell-crank lever H0 is connected to the quadrant II4 by a link H9. The link H9 is in the form' of a wire loop extending through an aperture III in the end of the arm H2 and loosely embracing a flat plate IIB having a depending slotted portion II9 fastened to the side of the quadrant I I4. The looped link H0 is relatively wide with respect to the arm II2 to permit the latter to slide laterally on the loop while the loop itself is adapted to slide longitudinally of the plate. The link II6 thus provides a flexible connection between the lever H0 and quadrant II4 so that the unit 4 may be angularly adjusted on the machine frame 2.

The quadrant I I4 is automatically raised when the yarn breaks or its supply is exhausted and when a package of predetermined size has been wound. Such actuating mechanism for the quadrant II4 isof usual construction including a yam-controlled drop-wire I20 pivotally mounted on the end of the quadrant H4 and a stop I2I adjustable along its length. When the yarn y breaks or its supply is exhausted one arm of the drop-wire I20 engages the toothed wheel 52 at the end of the cam-shaft 9 to thereby rock the quadrant H4 in a counter-clockwise direction about its pivot-stud II5. when the package is wound to a predetermined size a rib I22 on the traverse-frame 21 engages the wedge-shaped under side of the stop I2I to rock the quadrant H4 in a similar manner. In either case the rocking of the quadrant II4 lifts the bell-crank lever III to release the curved arm I25 which is thereupon rocked by the spring I03 to permit the spring I00 to slide the plunger-rod 96 of the circuit-breaker 9| to open the circuits. A suitable tensioning device I23 of usual construction mounted on the frame 2 operates on the yarn y as it feeds to the package being wound. The machine having now been described in detail its method of operation will be next explained.

To prepare the machine for a winding operation a suitable spindle 5 and cop-tube holder assembly are attached to the end of the armatureshaft 54. The unit 4 is swung about the fixed pivot-pin 59 on the frame 2 to adjust the angular relationship of the spindle 5 with respect to the bearing face 26 of the traverse-back 35 to correspond with the shape of the package to be wound. If the package is to be cylindrical the axis of the spindle 5 is set parallel with the hearing face 38 of the traverse-frame back 35 as explained above. When properly adjusted the unit 4 is clamped to the platform 3 by screwing down the nuts 64 against the feet 51 on the motor casing 53. During this adjustment of the unit 4 the position of the driving pulley 43 at the end of the drive-shaft extension 8 of the armatureshaft 54 may be altered somewhat with respect to the driven pulley 42 but the gear-housing automatically assumes the proper relationship to tension the belt 44 under the action of the weight The machine is then ready to commence a winding operation. A cop-tube C is applied to the spindle 5 and the split end of the spindle expanded by means of the expansion screw 83. With the machine prepared as above-described the winding operation proceeds in the usual manner as next explained. The yarn 11 is drawn up from its source of supply, not herein shown, led through the tensioning device I23 and across the drop-wire I20 at the end of the quadrant II4, then through the thread-guide groove 20 and its end attached to the cop-tube C. The control handle I04 is then rocked in a clockwise direction, as viewed in Fig. 1, which causes the end of the lever IIII to engage the push-button 00 and depress the plunger-rod 00 of the circuit-breaker SI. With the rod 96 depressed the conductors 0'! bridge the contact-fingers 84 and 95 in the casing 93 to close the circuits to the motor. As the handle I04 is rocked in the manner explained the lug I08 at the end of the curved arm I20 slides over the lug I09 on the pivoted bell-crank lever IIO into locking engagement therewith to maintain the circuit-breaker OI closed. The closing of the circuits energizes the motor to rotate its armature-shaft 54 and the spindle 5 and wind the yarn on the periphery of the cop-tube C. Due to the driving connection between the drive-shaft extension 6 and the cam-shaft 9 the cam I5 is rotated to reciprocate the traverse-rod 2I to thereby cause the thread-guide I8 to traverse the yarn to wind a package in the normal manner. The winding continues until the yarn breaks, its supply is exhausted or a package of predetermined size is completed. If the yarn y breaks the drop-wire I20 at the end of the quadrant II 4 is released to engage the toothed wheel 52 which causes the quadrant and bell-crank lever II 0 to be rocked to disengage the detents I08 and I09. The springs I00 and I03 then act to rock the lever IM and actuate the plunger-rod 90 of the circuitbreaker SI to open the motor circuits. Simultaneously with the actuation of the circultbreaker 9| the brake-shoe H3 is applied to the wheel 80 on the shaft 54 to arrest its rotation. When a package of predetermined size has been wound the traverse-frame 2'! will have been rocked about the cam-shaft 9 to a position where the rib I22 engages the adjustable stop I2I on the quadrant II4. Engagement of the stop I2I in this manner causes the quadrant II4 to be raised to effect the opening of the circuits and the application of the brake in the same manner to arrest the operation of the machine.

To adjust the winding machine for winding a conical package the nuts 64 are loosened on the bolts 6i and the unit 4 turned about the fixed pivot-pin 59 to the proper angular relationship with respect to the traverse-frame back 35. The nuts 64 are then screwed down on the bolts GI to clamp the unit 4 in adjusted position, it being understood that a spindle 5 with a tapered or conical holder 1 such as shown in Fig. 4 is first attached to the armature-shaft 54. During this angular adjustment of the unit 4 the arm II2 slides on the link H5 and the link adjusts itself on the plate H8 to the proper position as shown in Figs. 3 and 4. The link H6 thus provides a flexible connection between the separate elements of the circuit-breaker actuating mechanism which is self-adjusting to compensate for the different angular positions of the unit 4 with respect to the traverse-frame 21. With the machine adjusted as last described a conical coptube C is applied to the holder I and the latter expanded to grip the tube by rocking the handle I04 on the pin I24 to slide the sleeve 89.

The invention and its mode of operation having now been described, it will be observed that a winding machine of relatively simple construction is provided in which the winding-spindle is adapted to be readily and quickly adjusted to alter its angular relation with respect to the traversing mechanism so that either cylindrical or conical packages of any degree of taper may be wound. It will further be observed that each winding head has a separate winding unit with an individual motor drive thereby eliminating the usual belts, pulleys, counter-shafts, belt-shifters and clutches. It will still further be observed that the present invention provides a construction and arrangement of the winding machine which permits angular adjustment of the spindle without altering or affecting the starting and stopping control mechanism or its automaticallyoperated actuating means.

While I have herein described and illustrated a preferred form of construction of the machine, it is to be understood that modifications may be made in the structure and arrangement of the elements thereof without departing from the spirit or scope of the invention.
